Prettier features and specs

Consistency
Ensures a uniform code style across different files and projects, reducing code review conflicts and making it easier for team members to work on the same codebase.
Time-saving
Automates code formatting, which saves developers time that they would otherwise spend on manually formatting code.
Integrations
Works well with various code editors, IDEs, and continuous integration tools, making it easy to integrate into existing workflows.
Language Support
Supports a wide range of programming languages and file types beyond JavaScript, including TypeScript, CSS, HTML, Markdown, JSON, and more.
Community and Documentation
Backed by a strong community and comprehensive documentation that provide quick solutions and guide you through setup and customization.

Possible disadvantages of Prettier

Lack of Customization
Prettier enforces a specific set of rules and offers limited customization options compared to other linters or formatters, which may not satisfy all coding style preferences.
Learning Curve
New users may face a learning curve when configuring and integrating Prettier into their existing workflow, especially if they are not familiar with code formatters.
Performance Overhead
Running Prettier on large projects can introduce performance overhead, particularly during automated tasks like pre-commit hooks or continuous integration processes.
Conflict with Existing Tools
May conflict with other code linters and formatters, requiring additional configuration to ensure compatibility and avoid duplicated efforts.

TOML features and specs

Human Readable
TOML is designed to be easy to read and write due to its simplistic syntax, which is intuitive for humans.
Explicit Data Types
TOML supports various data types including integers, floats, strings, dates, and arrays, which helps in expressing configurations precisely.
Hierarchical Configuration
Allows for nested key-value pairs through its table and array of tables structures, providing a clear way to represent hierarchical data.
Standardized Specification
TOML is guided by a well-defined specification which ensures consistency across different implementations.
Lightweight
It is a minimal and straightforward format that doesn’t require much overhead compared to some other configuration formats.

Possible disadvantages of TOML

Limited Complex Data Structures
TOML is not suited for highly complex data structures, which might make it less ideal for certain advanced configurations.
Lacks Scalability Features
With limited support for advanced features such as conditional configuration or dynamic data, it might not scale well for very large configurations.
Not as Widely Adopted
Compared to formats like JSON or YAML, TOML may have less community support and fewer libraries and tools available across various programming environments.
No Native Implementation in Some Languages
Certain programming environments do not offer native TOML parsing support, requiring third-party libraries which might affect performance or security.

Prettier mentions (304)

Visual friction in development
Line length, spacing, and indentation matter. My preference for code is roughly 80 to 110 characters. Longer lines become tiring to scan, while very short lines can create excessive wrapping. For formatting, tools like Prettier reduce debate and keep code visually consistent across contributors. - Source: dev.to / about 1 month ago
How to Build a Dependency Map of a Legacy Codebase Using AI Tools
137Foundry provides legacy modernization services that include dependency mapping as a foundational assessment phase. Prettier and ESLint are useful companion tools for enforcing code style consistency as the refactoring proceeds. Node.js and Python.org official documentation are authoritative references for understanding the import and module systems of those runtimes. - Source: dev.to / 3 months ago
How to Prepare a Legacy Codebase for AI-Assisted Refactoring
Prettier and ESLint are useful tools for establishing consistent code style as a baseline before starting structural refactoring - style differences in a diff make behavioral changes harder to spot. OWASP provides useful checklists for security-critical code review that apply directly to the critical path review step. - Source: dev.to / 3 months ago
How I Automated My Entire Claude Code Workflow with Hooks
The matcher field takes a regex pattern. Edit|Write means this hook only fires when the Edit or Write tool is used. Claude running Bash, Read, or any other tool won't trigger it. The command itself uses jq to extract the file path from the tool input JSON, then pipes it to Prettier. Every file Claude touches gets formatted automatically. - Source: dev.to / 5 months ago
The Unix Philosophy for Agentic Coding
The better approach: let the agent write code however it wants, then run Prettier, Black, Ruff, or ESLint. Zero ambiguity. The agent doesn't need to think about formatting at all, which means fewer tokens spent and fewer decisions that could go wrong. - Source: dev.to / 5 months ago

My open source project was stolen and relicensed by a YC company
Some 15 years ago, I made a small configuration language: https://github.com/Respect/Config/blob/master/docs/README.md -- You could say that is just a coincidence, and it's an obvious idea that anyone could have had. But then again, also around that time, a sibling component for the configuration language was featured on "The Changelog" (then, a very popular website featuring interesting projects).... - Source: Hacker News / about 1 year ago
Let's meet Black: Python Code Formatting
Black uses by default the pyproject.toml file. This file contains a section for each different tool we want to use. The use of a configuration file like pyproject.toml is quite a good choice and helps the contributors to use the same tools and configurations you're using. - Source: dev.to / over 2 years ago
ML Configuration Management
Accessing the rest of the relevant variables is based on the various sections in the toml file. For example, referencing the Production Service Account (SA) will be by accessing the SERVICE_ACCOUNT variable which is under the [prd] section. - Source: dev.to / about 4 years ago
Get good Git info from Hugo
In your project config file, set enableGitInfo to true (here, I’m showing the Hugo default of TOML, although my own config file is actually YAML):. - Source: dev.to / about 4 years ago

For config file use case I cannot recommend enough TOML. Source: over 4 years ago
